WALTER E. CHRISTIAN, or" KENOSBA, Wisconsin, Assmnon. To THE BADGERBRASS mmuraoruame oomrAn'Y, or KENOSHA, WISCONSEN, A CORPORATION OF WIS-oonsn v i LAMP.

PatentedMar. 4, 1913.

Application filed June 17, 1912-. Serial No. 704,046.

though in its broader aspects the invention is'not necessarily solimited;

The salient object of theinvention is to provide, in a construction ofthe above character, simple and improved means for detachably lockin thereflector body to the door frame an at the same time rigidly confiningthe front glass or crystal in position. f V

Subsidiary objects are to provide a construction in which the reflectormay be readily locked to the door structure or detached therefrom, andwithout the .aid

of screws, bolts or other extraneous fastening devices; to provide aconstruction in which the reflector is provided with a plurality ofpivoted fingers or latch members adapted to havespring-lockingengagem'ent with slotted striker members carried by thedoor body; to provide a construction in which these locking devices areeffectively concealed within the lamp and yet ready access may be hadthereto by merely opening the door and in general to provide aneconomical and yet effective structure of the character referred to.-

The invention consists in the matters hereinafter described, and moreparticularly pointed out in the appended claims.

In the drawings'Figure 1. is a horizontal sectional view of an electriclamp equipped with my invention; Fig.2 is a vertical sec tional viewtaken on lines 22 of Fig. 1 and looking in the direction of the arrows;Fig. 3 is a fragmentary detail view showing one of the pivoted latchmembers; and Fig. 4 is a similar view showing one of the coiipe'ratingslotted striker members.

Referring to the drawing,1 designates the lamp body, to which is hinged,as shown at 2, the door frame 3, which in he present instance comprisesa ring 4 provided at its door is locked in closed position by means of ascrew" 6 and nut 7, the former being rigidly fixed in the boss 8 securedto the outer edge of the ring 4. When thedoor is closed, the 'screw lieswithin a forked bracket 9 rivetedto the outer side of the lamp body, asshown at 10. The door may be locked or opened by merely turning the nut7. The lamp is supported by means of the usual bracket 11 and confining.screw 12, the bracket fitting over a post (not shown) carried by the carbody.

Within the lamp body is seated the con.- cave reflector 13, the rear endof which is apertured to receive a socket member 14,

outer edge with an inturned flange 5. The i within which is sup ortedsuitable electrical connections 15 for t e bulb 162 These parts,however, form no part of thepresent invention, and need not be describedin detail.

As is seen more clearly in Fig. 1, the outer edge of the curvedreflector 13 is provided with an annular rim or flange 17 The frontglass or crystal 18 is secured between this flange 17 and the member 5of the door frame by the novel mechanism now to be described. To theflange or rim 17 are secured a plurality of circumferentially disposedsupportin blocks 19, to each of which iis pivoted, as s own at 20, aspring latch member 21.. The outer side of each of these latch members21 is provided with a locking lug 22, and at its free end each latchmember is turned up to form an ear23 by which the latch member can bemore readily forced into or out of locking position. As shown moreclearly in Fig. 3, the main'body of the latch-member is inclined awayfrom the supporting blocks 19, the arrangement being such that the latchmembers normally spring rearwardly or away from the blocks 19. Each ofthe latch members 21 is adapted to have lockingengagement with acorresponding striker member 24 which is secured to the inner side ofthe ring 4 of the door structure. Each of these striker members '24: isprovided at its inner face with a-recess or slot 25 for receiving thelugs 22 of the latch members.

In looking the reflector to the door structure, the'glass or crystal isfirst inserted in place and the reflector turned until the lugs 22 ofthe latch member are opposite the cor-. responding slots 25 of thestrikers. By

pressing on the inclined ears 23 the latch the slots members will beforced downwardly and at the same time swing on their pivotssufficiently for the lugs 22 to enter the slots 25. When pressure isreleased the lugs automatically snap into effective locking engagementwith the striker members. It is to be noted that-the ears 23 are soarranged relative to the pivoted latch members that by pressing down onthe ears the latch members are not only forced down\\-'ardly, butinwardly sufficient for the lugs 22 to engage The latch members may bereleased by simply forcing the ears downwardly and outwardly until thelugs pass out of the slots.

The invention is not limited to the details of the invention shownexcept as set forth in the appended claims.

I claim my invention:

1. In a lamp, the combination with a body portion, of a door structuresecured thereto, a reflector within the lamp body and adapted to movewith the door structure, and means for detachably locking the reflectorto the door structure, com arising pivoted latch members secured tot ereflector and cooperating striker members carried by the door structure.

2. In a lamp, portion, of a door structure pivoted thereto, a reflectorwithin said lamp body and moving with the door structure, and means fordetachably securing the reflector to the door structure, comprising aplurality of resilient latch-members secured to the reflector, andcooperating striker members secured to the door structure and havingcooperative spring-locking engagement with said latch members.

3. In a lamp, the combination with a body portion, of a door membermovably connected thereto, a reflector member within said body portionand adapted to move with the door member, and means for detachablylocking said members together, comprising a plurality of spring latchescarriedby one member, and a plurality of striker members carried by theother member and havin spring-locking engagement with sai latches.

4. The con'ibination with a main body portion, of a member pivotallyconnected to said body portion, a second member within said lodyportion, and'means for detachably locking said members together,comprising pivoted spring latches carried by one of said members, andcooperating strikers carthe combination with a body ried by the other ofsaid members and adapted to have spring-locking engagement with saidlatches.

5.111 a lamp, the combination with a, main body portion open at itsouter end, of a door frame hinged to said body portion and comprising aring provided at its outer edge with an inturned flange, a reflectorwithin said body portion and provided at 'its outer edge with anoutturned flange, a

glass seated between said flanges, and means for locking the reflectorto the door frame, comprising a plurality of spring latch memberspivotally connected to sair outturned flange and provided withlocking-lugs, and a plurality of striker members secured to the innerside of said ring and slotted or recessed to receive the locking lugs ofsaidv latch members.

(3. In a lamp, the combination with a main body port-ion open at itsouter end, of a door frame hinged to said body portion and comprising aring provided at its outer edge with an inturned flange, a reflectorwithin said body portion and provided at its outer edge with anoutturned flange, a glass seated between said flanges, and means forlocking the reflector to the door frame, comprising a plurality ofslotted striker members secured to the side of said ring, and aplurality of latch members pivoted to the inner edge of said flange andeach comprising a spring body portion, an outturned lug adapted to havelocking engagement with the slot of the corresponding striker member,and an inclined ear portion secured to the outer edge of the latchmember.

7. In a lamp,- the combination with a main body portion, of a doormember piv oted thereto, a reflector member within said body portion, astriker carried by one of said members, a spring latch pivoted to theother of said members and adapted to have locking engageu'ient with saidstriker.

8. In a lamp, the combination with a main body portion, of a door memberpivoted thereto, a reflector member within said body portion, a strikercarried by one of said members, a spring latch pivoted to the other ofsaid members and adapted to have locking engagement with said striker,said latch having an inclined extension at its free end.
